Construction simulation is the virtual realization of the actual project construction process on the computer.Building geometric model and construction process model by BIM technology can realize real-time,interactive and realistic simulation of construction scheme,and then the existing construction program to verify,optimize and improve.BIMFILM is a simulation software that combines on site construction management that can be used for visual presentation of construction proposals and visual disclosure of construction safety techniques.BIMFILM combined with project-specific research technology to achieve the path,showing its simple operation,powerful,efficient rendering function,to solve the hydraulic engineering construction process optimization,construction process display to provide a new solution.
